Common Questions:

What size dumbbells should I buy?

You should pick a weight you are comfortable with, and one that you are able to perform between 10 and 15 repetitions for two or three sets.  Keep in mind, it is better to start any exercise program at a slower to moderate rate and then tailor the program to fit your individual need.  The beauty to a lighter weight is that there is still a benefit to working out with a lighter dumbbell and performing higher reps.  It is significantly more difficult, and potentially more injury prone, working out with too heavy a weight than too light a weight.  Starting lower and then working up to the heavier dumbbells sets is the preferred method for starting to build strength.
